Summary: | Provided is a mordenite zeolite which can be produced without using an organic structure-directing agent, and has superior multivalent metal cation exchange capability. The mordenite zeolite according to the present invention containing silicon, a divalent metal M and aluminum in a skeletal structure, wherein the mordenite zeolite has the following atomic ratios in the state of Na-form. The mordenite zeolite preferably has a BET specific surface area of 250 m2/g or more and 500 m2/g or less and a micropore volume of 0.07 cc/g or more and 0.25 cc/g or less in the state of Na-form or H-form. Si/(M+Al)=5 or more and 10 or less, M/(M+Al)=0.1 or more and less than 1, and Na/(M+Al)=1 or more and less than 2. |
